FCC Consumer Alert (U.S.)

Most users do not need a license to operate this wireless microphone system. Nevertheless, operating this microphone system without a license is subject to certain restrictions: the system may not cause harmful interference; it must operate at a low power level (not in excess of 50 milliwatts); and it has no protection from interference received from any other device. Purchasers should also be aware that the FCC is currently evaluating use of wireless microphone systems, and these rules are subject to change.

IMPORTANT

ULX-D 2.X firmware versions are incompatible with ULX-D or QLX-D 1.X firmware versions. To ensure all receivers and transmitters in a configuration function with each other, update all devices to the same firmware version.

KNOWN ISSUE

NOTES

ULXD1/2 transmitters used with receivers must be updated via IR sync. After a receiver is updated, follow these steps:

Go to the receiver menu: DEVICE UTILITIES > TX FW UPDATE

Align the infrared ports with the transmitter

Press ENTER

Maintain an IR connection when updating transmitter firmware via IR sync. In rare occasions, upgrades from 1.5.6 or earlier to 1.6.6 or later can cause transmitters to become non-responsive temporarily. If the update fails and the unit is non-responsive, resolve the issue by following these steps:

Using the Shure Update Utility, downgrade the firmware for the ULXD4/ULXD4D/ULXD4Q Receiver to 1.5.6 AND keep the desired transmitter firmware (1.6.6 or later).

Update the transmitter firmware to 1.6.6 or later via IR menu. From the receiver menu: DEVICE UTILITIES > TX FW UPDATE. Align the infrared ports with the transmitter and then press ENTER.

Upgrade receiver to 1.6.6 or later.

Improvements

Improved large-scale network stability: In some cases of very large installations with earlier firmware versions, units occasionally would drop off the network and not be visible via WWB6 or other remote networking access. Version 2.0.28 resolves the issue and increases overall network stability.

Added new frequency bands:

Europe: Z17: 1492 – 1525 MHz

Europe: Z18: 1785 – 1805 MHz
